fstorage write& Erase Interrupt not Triggered when BLE Init Called

[GSV R&D]

I have written a word (32 bites) in 0xFF000 using nrf_fstorage_write(),  When BLEInit(), nrf_fstorage_evt() callback not trigged, 

BLE_Sleept()

nrf_storage_write()

BLE_wakeup()

I noticed a few problems with your write_to_flash() implementation, please see diff below for details. I did not review the other functions in your code.
